Newton's Laws

Question 1

Newton’s first law of motion

Answer 1

An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force

Question 2

Newton’s second law of motion

Answer 2

• An unbalanced external force applied to a body at rest or in uniform motion will produce acceleration in the direction of the force
• The size of the acceleration depends on the mass of the object and the size of the force acting

Question 3

Formula of first law

Answer 3

Force = mass*acceleration

Question 4

Formula of second law

Answer 4

Acceleration = force/mass
